Does anyone know the difference between the two? other than the cast aluminum material being used to make it?

Skunk2 Pro Series Limited Edition Intake Manifold (D/B-series) - JDM Honda Parts USA

Skunk2 Pro Series Intake Manifold - D/B-series - JDM Honda Parts USA

the limited edition looks longer than the regular pro series. im planning on buying one and it says on the limited edition that:

D-series Intake Manifold Notes:
Not compatible with OEM D-series throttle body. Must use larger-bore Skunk2 throttle body or similar.
Not directly compatible with Civic Wagon or Wagovan; clearance modifications required.
Not directly compatible with '96-'00 Civic; brake proportioning valve and fuel filter clearance required.
Ideal for turbocharged and naturally aspirated applications.
66mm throttle body opening can be port-matched up to 70mm.

and im wondering if on the regular pro series(non lim edition) if it has the same fitment. like will the non lim edition have clearance issue with the fuel line and brake prop valve, and the stock tb not being compatible. Thanks

 

Not to sound like a jerk but why don't you contact Skunk2, they would have all the definite answers.

 

Same thing, different colors.

 

They added the word limited, painted it, and will charge you $60 more. You're welcome.
